Research Interests:
Dr. Tobias is a geochemist interested in the fate and transport of macroelements (e.g. carbon, nitrogen, and oxygen) in a variety of aquatic and near-shore marine habitats. Primary tools for inquiry include using stable isotopes at multiple spatial scales and enrichments, and integrating these system-scale measurements within element mass balances. Recent research has focused on removal of groundwater nitrogen loads by coastal salt marshes, constructing estuary-scale nitrogen budgets, examining coupled carbon and oxygen dynamics in alkaline streams, and developing techniques to measure reaction rates in the field across hydraulically active interfaces.
